Please take 1 minute, and really read the example solution
under problem #12. All of the other eight problems on the
sheet are solved in exactly the same way:
Multiply each side of the equation by the denominator of
the fraction ... the number under the variable (the letter).
This easy step will get you the answer to each of the
eight problems.
I can't help noticing that the title of the sheet is 'extra PRACTICE' .
If someone handed you the answers, then you would not get the
practice. That would be just like stealing from you, and would be
just plain mean.
Answer:
Step-by-step explanation:
The universal set, U is a set of all vehicles produced by the manufacturer.
U = red, blue and green vehicles(both cars and trucks)
B = all red vehicles produced by the manufacturer(both cars and trucks)
C = red, blue and green trucks
C ' = all elements that are not in C but are in the universal set
C ' = red, blue and green cars
B intersection C ' = all elements that are common to set B and set C '. Therefore,
B intersection C ' = red cars
They are all multiples of 12. 12x1, 12x2, 12x6, 12x24.
Answer:
76
Step-by-step explanation:
4^2 x 5^2 - 18^2
PEMDAS is our acronym for order of operations: Parentheses, exponents, multiplication, division, addition, subtraction.
Since we have no parentheses, we'll calculate the numbers and exponents (PEMDAS) first. "to the power of 2" is also called "squared" and means multiplying that number by itself.
(4x4) x (5x5) - (18x 18)
=16 x 25 - 324
Now we multiply: (PEMDAS)
= 400 - 324
then subtract: (PEMDAS)
=76
